The system works by employing a pressure-release function, not seen in the angling world until now. The latched lead clip will open once a hooked fish pulls against the angler, allowing the lead to drop free. By threading a Barrel Bead onto the leader above the Heli Safe, you will prevent the lead from discharging, should you pick up weed or other detritus on the retrieve. Once engaged in battle though, the bead will simply pull down and allow the lead to discharge.
